Perfect Pitch - Piano Notes 对比 Learn Your Keys 的使用情况和统计数据

Learn Your Keys does one thing—help you master keys and scales! When you started learning to play your instrument you probably played notes in C Major, the simplest scale using the white keys on a piano. Now you’re ready to learn about the other keys, like D Major and F# minor. This app helps you remember the notes in a key, where they appear on a staff (with the appropriate sharp or flat accidental) and what piano keys are used. Tap a note to see where it’s played on a piano. Or tap a piano key to see where the note appears on the staff. You will get used to hearing it so you’ll recognize it in the future. And as you start to learn your keys and scales you can see the actual note names on the staff, not just musical notation.
